“When James got that very strange rainbow clip, clothespin thing that they give, he was thinking of retiring at the time and so I sang it to dissuade him," said Aykroyd, repeating the lyrics, "If you leave me I’ll go crazy.’”

Aykroyd and Fallon both shared stories of Brown and took turns at imitating his voice. Fallon recalled the story when the late singer told actor Eddie Murphy to bury his money in the woods, “so the government doesn’t get it.”

"Get On Up" stars Chadwick Boseman and Octavia Spencer and follows the life of Brown from living in poverty to becoming an iconic singer.
